If you still have something from Union Bank and Trust
A lien that was never released
Union Bank and Trust failed on Jul 21, 1988. For a failed bank placed in FDIC receivership, the FDIC may be able to issue the lien release, if the loan was paid off to the bank before it failed or to the FDIC afterward. The FDIC says that where a failed bank had an acquirer, its records in most cases went to that acquirer. Here the chain from the acquirer leads to Arvest Bank, which is worth asking too.
Requests go through the FDIC Information and Support Center with the recorded mortgage or title, and proof of payoff. The FDIC says to allow 30 business days once it has every document, and does not take requests by phone or email. Questions: FDIC Resolution Inquiries, 888-206-4662, 8am–4pm Central on weekdays.
An old account, passbook or CD
When a healthy bank assumes a failed bank's deposits, insured depositors become its customers right away (here, First National Bank in Bartlesville). Start with Arvest Bank, and ask them to search under the name Union Bank and Trust.
This failure is older than the current federal rule on unclaimed deposits (mid-1993), so different rules apply. Search FDIC unclaimed funds search, search the unclaimed-property program of the state of the owner's last known address on the bank's records, and ask FDIC Resolution Inquiries at 888-206-4662 what applies to this institution.
A safe deposit box
The FDIC says that when a healthy bank assumes a failed bank's deposits, the branches usually reopen the next business day with box access. Today, ask Arvest Bank. A box abandoned for years may have been turned over to the state's unclaimed-property program.
Box contents are not covered by FDIC insurance.
Not sure this is your bank?
Many banks shared a name. Match the city and the years above against your paperwork, or search again with the town.
Credit unions were never FDIC-insured and are not in this record; the NCUA credit union lookup covers those. Banks that closed before about 1970 are not in the FDIC's list either.
One caution: banks also sell single branches. If the office you used was sold to a different bank along the way, the account went with the branch, not with this chain.
